Intervention Options

A multitude of options exists to protect, preserve and display exposed archaeological sites; each suggests certain advantages and disadvantages.


  Soft Capping
Soft capping replaces hard caps with vegetation planted on top of layers of soil, gravel, and geo¬≠synthetics.¬† The idea is to prevent water penetration and to reduce thermal fluctuations by taking advantage of plants' abilities to utilize the water and provide a protective barrier on the wall top.  The concept is very similar to green roof technology that has gained increased popularity in recent years.
